DETACHABLE FLOTVPOIN'I.

Application filed August 28, 1922.

To all 2072 0722 it may concern Be it known that I, l VILLIAM H. KLINE, a citizen of the llnited States, residing at Herscher, in the county of Kankake'e and State of Illinois, have invented certain new and useful Improvements: in Detachable Plowpoints, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to plow points, and has for its object to provide a device of this character that may be readily attached and detached from a plow share without requiring removal of the plow share from the frame or standard of the plow.

Another object of the invention is to provide a plow point of this character which not only protects the end portion or point of the plow share, but wherein the usual motion of the plow, that is, in a forward direction, serves to retain the point in engagement with the share.

It is also an object of the invention to provide a plow point of this character which is not only arranged to receive the point or end portion of the share, but provided with means for also securing the point to the plow share.

With these and other objects in view, the

$0 invention consists in the improved construction and arrangement of parts to be hereinafter more particularly described, fully claimed and illustrated in the accompanying drawings, in which Figure 1 is a bottom plan view of a plow share showing the plow point attached;

Figure 2 is a side view of the plow point;

Figure 3 is a rear end elevation of the plow point; and

Figure 4 is a section taken on the line k4: of Figure 1.

Referring to the drawings, 5 designates a conventional form of plow share including an end portion or point 6 and a sole flange 7. The end portion 6 is tapered from the central portion of the share to the extremity of the end, thus forming a point. By the tapered side portions of the end portion 6 of the share, a wedge is substantially formed. This wedge formation is utilized by the present invention in a manner to be hereinafter described. The tapered or wedge formation of the plow share just mentioned is, of course, common to the plow shares now is use.

Serial No. 58 L805.

In connection with "he share 5, a novel plow point member is provided, said member including; a base member 8 constructed in accordance with the shape of the iandside portion of the share and sole flange 7. he forward end portion 9 of the base 8 has one 01 its longitudinal edges curved in accordance with the curvature of the plow share.

Projecting from the longitudinal edges of the end portions 8 and 9 are walls 10 and 11, the end portions 12 of said walls merging at the extremity of the end p rtion 9 of the base member. The walls are also inclined inwardly toward each other and merge at their upper edges as at 13. this means the tront ends and upper edges of the walls 10 and 11 are formed integral so as to substantially provide a sharp edge which serves as the main point of the plow. In view of the particular arrangement of the base 8, the walls, in addition to inclining toward each other vertically, also incline toward each other horizontally, in order to permit the'end portions 12 of said walls to merge. By this means the walls 10 and 11 cooperate to substantially provide a socket or compartment 14: which corre sponds to the shape of the wedge end portion 6 of the plow share and of a size to snugly engage the end portion 6. It will be noted that the inner end portions 14 of the walls 10 and 11 substantially terminate at the central portion of the base member 8, thus permitting the base member to extend a considerable distance inwardly of the plow share. The inner end portion 15 of the base 8 is curved in accordance with the contour of the land side portion of the plow share, while projecting from the side of the end portion 15, remote from the curved portion thereof, is an extension 16, said extension being disposed at right angles to the base member 8 and having its extremity 17 extended in spaced parallel relation to the base member 8 and toward the curved portion of the end 15. The end portion 17 of the extension 16 cooperates with the end portion 15 of the base to provide a clip adapted to receive a portion of the sole flange 7 of the plow share. The end portion 17 of the extension is also provided with a threaded opening 18, adapted to receive a set screw 19.

In attaching the device to a share it is only necessary to position the clip so that it will receive the sole flange, thus permitting the end portion 6 to'be positioned adjacent the entrance to the socket. The plow point is then moved toward the plow share so as to permit the socket formed by the walls 10 and 11 to entirely enclose the end portion 6 of the share. Continued movement of the plow point on the share will substantially cause the socket member to bind on the plow share, in view of the wedge shaped formation of the end portion 6. After the plow point has reached the limit of its movement relative to the plow share, the set screw 19 is adjusted so as to urge the sole flange into engagement with the body portion 8 of the plow point, thereby positively securing the plow point to the share.

From the foregoing it will be readily seen that this invention provides a novel form of plow point capable of being readily applied to the conventional forms of plow shares now in use without requiring alteration of the plow'share in any manner, and without requiring the services of a skilled person. In addition to this, there is no possibility of the plow point becoming accidentally disen gaged from the plow share, as the socket member, together with the wedge shaped formation of the plow share, holds the point rigid so that it substantially forms a part of the plow share. Regardless of this novel fastening means the clip provided at the end of the plow prevents breaking of the binding engagement between the socket member and the end portion 6 of the share in view of the fact that it prevents accidental removal of the share from the socket through the medium of the set screw. All of these features are possessed by a device that can 1 ,eeasee body member having one end portion thereof formed into a pointed socket adapted to receive a portion of the plow share, the opposite end portion of said body member having a clip arranged to engage the sole flange of the plow share, and fastening means carried by the clip for engagement with the sole flange. 7

8. In combination with a plow share including a sole flange, a plow point including a body member arranged to engage the under side of the plow share and sole flange, one end portion of said body member having a wedge shaped socket member, the exterior edges of said socket member being sharpened, said socket member being adapted to receive and frictionally engage the forward end portion of the plow share, an extension carried by the opposite end portion of the body member, said extension being formed into a clip adapted to extend over the sole flange, and a set screw carried by said extension for urging the body member into e11- gagement with the plow share. 7

In testimony whereof I hereunto alfix my signature.

WILLIAM H. KLINE.
